fsadm — utility to resize or check filesystem on a
device
- fsadm
- [options] check device
- fsadm
- [options] resize device [new_size]
fsadm utility checks or resizes the filesystem on a device (can be
also dm-crypt encrypted device). It tries to use the same API for
ext2, ext3, ext4, ReiserFS and XFS
filesystem.
- -e|--ext-offline
- Unmount ext2/ext3/ext4 filesystem before doing resize.
- -f|--force
- Bypass some sanity checks.
- -h|--help
- Display the help text.
- -l|--lvresize
- Resize also given lvm2 logical volume. More volume management
functionality is provided with complementary lvresize(8) and the
option -r|--resizefs.
- -n|--dry-run
- Print commands without running them.
- -v|--verbose
- Be more verbose.
- -y|--yes
- Answer "yes" at any prompts.
- -c|--cryptresize
- Resize dm-crypt mapping together with filesystem detected on the device.
The dm-crypt device must be recognizable by cryptsetup(8).
- new_size[B|K|M|G|T|P|E]
- Absolute number of filesystem blocks to be in the filesystem, or an
absolute size using a suffix (in powers of 1024). If new_size is not
supplied, the whole device is used.
On successful completion, the status code is 0. A status code of 2
indicates the operation was interrupted by the user. A status code of 3
indicates the requested check operation could not be performed because the
filesystem is mounted and does not support an online fsck(8). A
status code of 1 is used for other failures.
Resize the filesystem on logical volume /dev/vg/test to
1000 megabytes. If /dev/vg/test contains ext2/ext3/ext4 filesystem it
will be unmounted prior the resize. All [y/n] questions will be answered
'y'.
# fsadm -e -y resize /dev/vg/test 1000M
- TMPDIR
- The temporary directory name for mount points. Defaults to
"/tmp".
- DM_DEV_DIR
- The device directory name. Defaults to "/dev" and must be
an absolute path.
